KH 36 splined hubs creaking

This has been done before but I cannot find the answers easily using the search option.
Has any one got definitive answers or solutions to creaking and clicking KH 05 hubs and spokes?
Look forward to your replies.

Thanks

Thanks for the quick reply.
What is the go with copper based grease? Any one know?

I always just used to remove the cranks and liberally apply grease to the splines, this would stop the creaking for several months at a time.
